Field work with Nature Live

It's taken a while for me to get back into the swing of things after my return to London, but at long last here's what happened on the last few, hectic days in Mexico, which included one last day in the field to collect our final samples:

 

A 05:00 start was a harsh way to take on the most challenging climb of the trip but by then Chiara and Dave were ready. Although as they trooped out to the jeep, heavy limbed, it was hard to discern that they knew it. Your devoted reporter remained on the bench in Amecameca on the basis of a four-only-in-the-jeep rule; jealous of the landscapes the rest of Team Popo would see and the last chance at such physical endeavour.

 

I wanted to leave town exhausted but I'd just have to leave educated and elated instead. On writing and curation duties, I was to source rock-packing materials, a somewhat vital task, so was spurred on in the role. In preparation, I demolished huevos rancheros and set off with the sun on my face, a less than ideal command of the language and immense purpose.

Forget what you know about eating fried eggs, tortillas, cream and green chilli sauce at different times.

When riding other animals, it's customary to do it contraflow to heavy traffic. 

 

My insight into the last day of scientific field work on Popo came as the team arrived back at base early in the evening. They looked at the peak of their exhaustion. We dined quietly but when asked how the day went, Dave gave a dazzling smile and explained how in his element he was. 'Where did your energy come from?' I asked. 'I don't know, he replied. It was some kind of euphoria. I just kept on going, following my body rhythms.'

 

Reaching their highest altitude yet of 4,474m, Chiara too had a strong final day in the field. She described how for her, Hugo had set the pace and by 'making small footsteps in his wake', she could maintain the energy to make it. 'Without Hugo, I would have failed,' she said, with what's become her trademark grin and shrug of the shoulders.

I'll name that layer in one.


Chiara's research will very much depend on the data she generates once she's tested these samples back at the Museum. However, as the week progressed it's clear Dave can already see how his work here will enhance the Museum's collections. The Popo samples from this trip will have context of the type he rarely sees in the collection, with his photographs and field sketches giving an exact visual of the make-up of each outcrop.

 

This, along with the GPS and field notes places the sample more firmly at it's location and - to fully understand Popo - this helps immensely. 'It was also great to get back into making sketches,' he says. 'To be here to collect from the source is invaluable. I have much more to information to offer those wanting to use these collections now.'

Dave tells me his drawings have been 'enhanced' by years of doodling with his two kids.

Local dining requires rapid response paperware.... In truth, our visit to procure more packaging for the specimens.

Lost Highway: Laden with rocks, Dave and Chiara's taxi takes ten wrong turns too many. Mostly to the right.

 

If any of you have seen the film, The Canonball Run, you will have some insight into the way Mexican highways and byways work. As Chiara and Dave's taxi heads for Mexico City and the beginning of our journey home, we spot a car boot full of people with their legs sticking out, the vehicle swerving between traffic. My palms begin to sweat at the sight.

 

The 90 minute journey extends to a joyful five hours as the taxi gets lost and our Sat Nav diverts us to the more 'exhilarating' - i.e. terrifying - parts of town. A lifetime later, we've booked into our hotel and hit the streets of the busiest city I've ever been to and spend the evening re-living the highs and lows of the trip. The sheer volume of people traffic serves only to remind us of the dangers of Popo, a mere 70 kilometres away. It also makes me think of how vital Chiara's research could one day be in predicting their safety.

Following an early start watching Hornbills yesterday and a late night linking live (via satellite) to the Museum in London, everyone was looking forward to a lie-in this morning….but no-one had explained this to the local Bearded Pigs.  At about 5am there was a huge commotion with snorting and bellowing right outside our bunkhouse, goodness knows what about, but Kerry was the only person not to be woken by it!

A regular visitor to the Studies Centre, the Bearded Pigs are aptly named.

 

Today is our final day in Maliau and everyone has been busy packing and preparing for the journey to Kota Kinabalu, the capital city of Sabah.  Not only do we need to worry about how everything will fit back in our suitcases/bags, the samples of invertebrates and lichens need to be carefully sorted and packed, to ensure they are not damaged on the long (inevitably bumpy) car journey tomorrow. 

 

 

Lichens that are going to be used by Holger and Pat, who will identify and describe them, need to be carefully prepared and packed.  I asked Pat how she goes about doing this…

 

The lichens will all be added to collections held at the Universiti Malaysia Sabah (UMS) and then those that require further study will be sent to the Natural History Museum (in London) for Pat and Holger to identify and where necessary describe new species to science.

Kishneth’s bark samples cover the floor of the laboratory, ready to be packed and transported back to Kota Kinabalu.

 

Meanwhile, the sections of tree bark and further (cross-referenced) samples of lichens will be analysed by Charles and his team of chemists, including Kishneth, at UMS and their chemistry studied.

Elsewhere, Dan, Kerry and Keiron have been emptying the final Winkler bags and gathering their various samples together.  There’s a noticeable difference in the volume of material that the different traps have collected.

A ‘line-up’ of samples – a pair of Malaise trap samples on the left, SLAM traps, pitfall traps, and finally a pair of leaf litter samples on the far right.

 

The Malaise traps have been particularly successful in sampling a large number of forest invertebrates, while the pitfall traps have caught some of the larger specimens.

While walking towards the forest today for a final stroll beneath the mighty Dipterocarp trees, I couldn’t help but notice a small flowering plant on the side of the road.  Particularly memorable because of what happens when you touch it….

 

 

The leaves of Mimosa pudica quickly fold inwards or droop when touched.

 

Mimosa pudica, while intriguing, shouldn’t be here.  It is a species native to South and Central America, but is an invasive weed across much of the tropics.  It seems incredible that such a small plant could have made it all the way from South America to the depths of Sabah in Borneo, and yet it’s not an uncommon tale.

 

We’re looking forward to a change of scenery when we get to Kota Kinabalu tomorrow but for now, with the closest village 2 hours drive away, games of cards and charades are the mainstay of our evening’s entertainment.

It’s a film…..four words….
